IMPROVEMENT IN BUCKLES.

Specification forming part of Letters Patent N 0. 170,831., dated December7, 1875; application filed October 20, 1875.

To all whom it may concern:

Be it known that I, ALBION DYKE,Of N ashua, in thecounty of Hillsborough, State of New Hampshire, have invented a certain new and useful Improvement in Buckles, of which the following is adescription sufficiently full clear, and exact to enable any person skilled in the art or science to which my invention appertains to make and use the same, reference being had to the accompanying drawing forming a part of this specification, in which- Figure 1 is an isometrical perspective view. My invention relates more especially to buckles of the larger sizes, or those designed for heavy work 5 and consists in a novel constrnction and arrangement of the parts, by which a stronger and more effective device of this character is produced than is now in common use.

The nature and operation of my invention will be readily obvious to all conversant with such matters from the following description.

In the drawing, A represents the body of the buckle, which is of the ordinary construction, and provided with the hinged tongue D. The side pieces of the body are connected by a cross bar, B, preferably made or cast integral with the same, and having a notch or 111- dentation, 0, into which the tongue falls when the buckle is in use. This bar is slightly crowning, rising higher at its center than the plane of the side pieces, and has angular or sharp edges on its upper surface, to increase the friction between the bar and strap when the buckle is in use. The object of the crossbar is to release the strain, which usually falls entirely upon the tongue, and also to strengthen the body, thus not only enabling a much smaller tongue to be used, but greatly increas' manner. It, now, the strap is drawn through the buckle, it will be forced down upon the cross-bar, by which it will be caught and held in such a manner that nearly the entire strain, which would otherwise fall upon the tongue, will be exerted on the bar.

It will be evident that the bar, instead of having the sharp or angular edges, as described, may be constructed with a wedgeshaped edge upon its upper or outer side and effect the same result without departing from the spirit of my invention. 1

Having thus explained my invention, what I claim is In a buckle, substantially such as described, the cross-barB, crowning near its center, and provided with the notch G, substantially as set forth and specified.
